@LeEpicMinecrafter His answers were all off by one question on the answer sheet, so they were all marked wrong. So, he's got supplemental lessons for failing the exam.
@APersonOnAComp a decent teacher would have forgiven the mistake and adjusted the score to recognize that they didn't get the answer wrong, they just were in the wrong spots. Unless the tests are all scantrons, I'm pretty sure it was a teacher who pointed out the mistake to him.
I'll never understand this misplacement issue that lead to failing tests. Where I live they would have see the problem score accordingly and probably apply a malus to the final score. Unless the test was a MCQ, in that case a failure is inevitable.
